Dear all,

I see the following configuration example in Cisco web site.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t4/ft_afrts.htm

So I would like to use the followings. But one question to ask, if to
prevent routing traffic does not drop, is it suitable use the DE bit or to
use priority queue?

interface serial0
 encapsulation frame-relay
 frame-relay traffic-shaping
 frame-relay interface-dlci 200
 class adjust_vc_class_rate
!
map-class frame-relay adjust_vc_class_rate
 frame-relay cir 64000
 frame-relay mincir 32000
 frame-relay adaptive-shaping interface-congestion 10
